St. Panteleimon

The Church of Saint Panteleimon is a late Byzantine church in Thessaloniki, Greece, and a UNESCO World Heritage Site.

The church lies in the eastern part of the old city, near the Tomb of Galerius, at the junction of Iasonidou and Arrianou streets. Its current dedication to Saint Panteleimon was given to the church after the end of Ottoman rule in 1912, and its original dedication is therefore disputed. In Ottoman times, it was converted into a mosque in 1548 and became known as Ishakiye Camii, which in the prevailing scholarly interpretation points to an identification with the late Byzantine Monastery of the Virgin Peribleptos, also known as the Monastery of Kyr Isaac after its founder Jacob, who was the city's metropolitan bishop in 1295–1315 and became a monk with the monastic name of Isaac.
